AUTOMOBILE-HOOD;

Specification of Letters Patent. I Patented B133 15, 1917.

Application filed January 5, 1917. Serial No. 140,729.

To all whom it may concern.

Be it known that I, LORENZO NonvEL-L,

a citizen of the lhlitcdlStates of America, residing at the city of St. Louis, State of Missouri, United States of America, have invented a certain new and useful Automobile-Hood, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to means for preventing the rapid dissipation of heat of automobile engines during cold weather, and the protection of the exterior finish of the metallic engine covers or hoods generally employed. a l

The general practice at present is to apply a cover to the exterior of the engine hood for retaining heat in cold Weather. Such covers, however, are expensive and soon become unsightly in appearance. It is also very difficult to make-such covers fit properly and to retain them in position, and they are subject to the further objec tion that dust, collecting between the cover andthe hood, mars the exterior finish of the hood. It has heretofore been proposed to overcome these disadvantages by placing an insulating covering underneath the hood,

such covering consisting either of a perma-' nen'tly atta'ched, continuous lining for the hood, or a separate and independent hood of insulating material. The separate hood is, however, expensive and renders access to the engine inconvenient, and a permanent insulating lining for theregular hoodis impracticable, because during the greater cross section. F ig. a is a'detail illustrating a modified form of clamp holding means.

The metal hood 1 is formed in four-sections hinged together according to the usual practice.

'To each of these sections and at the lower edges thereof are riveted, or otherwise suitably fastened, two-or more clamping members 2 spaced apart as shown and extending upwardly across the. inner surfaces of the hood sections. The clamping members 2, Which are attached'to the two upper sections of the hood,'are adapted to extend into a' space between the hood sections and the circular extensions thereof which form the hinges, and are supported by these hinges. In case the extensions of the hood sections forming the hinges are positioned above the upper surface of the hood, as shown in Fig. i, retaining members 3 for the. clamps, as shown inl ig. 4, may be provided. The clamping members are so shaped and positioned with reference to the hood sections as. to permit the insertion of sheets of insulating material 4 between them and the hood sections, and to hold this insulating material in position. The sheets i may be of asbestos, for example, which is readily obtainable and can be cut to fit the sections 'that when either half of the hood is turned part of the year in temperate climates it is desirable to facilitate the dissipation of the heat of the engine as much as possible.

It is the object of my invention to pi'ovide a form of construction in which the insulating means may be as readily attached and detached as the present generally employed form of external covering, and a construe,

tion which requires-only slight mechanical additions to the usual form of hood to fit it for the reception of the insulatingmeans which any automobile owner may form from material easily obtainable.

In the accompanying drawings, Figure l is a side view of a hood embodying my invention; Fig. 2 is a top view, and Fig. 3 a

of any hood. The upper ends of the clamping members 2 can'be engaged and disen' gaged from the shoulders 3, or the hinge portion 5, by movement in a horizontal direction as they are sufliciently resilient to permit this,

It will be noted that permanent attachment of the clamps at the lower portion of the hood sections puts them in such position up the asbestos sheets can be readily inserted and are positively held from downward movement in the normal position of the hood by resting upon the permanently at tached portion of the clamps, rather. than byifricti on due to the pressure of the clamps.

The practical advantages of the construction described are numerous. The exterior appearance of the automobile is not affected. "The insulatingmaterial not only retains the heat of the engine, and thus serves the purpose of the present forms of exteriorhood coverings, but also prevents the hood from becoming so warm that snow and ice coming in contact therewith would cause cracking of the finish. Further, the insu others.

Having fully described my invention, what I claim as'new and desire to secure by Letters Patent of the United States is:

v l. The combination of an automobile hood formed in sections, sections of insulating material for the hood sections, and meanscarried by the hood sections for removably supporting the lnsulatlng sectlons adjacent to the inner sides of the hood sections.

2. The combination of an automobile hood formed in sections, a separate section of insulating material for each hood section, a plu 'ality of clamping members each attached to the lower portion of a hood section and extending upwardly to removably support the insulating sections adjacent to the inner sides of the hood sections.

3. The combination of hood formed in sections, a separate section 0t insulating material for each hood section, clamping members attached to the lower portion of each hood section, and retaining means adjacent to the upper edges of the upper hood sections, said clamping members extending across the said sections and engaging with the retaining means.

4. The combination of an automobile hood formed in sections, a separate section of insulating material for each hood section, clamping members attached to the lower poi-tion of each hood section, and retaining means adjacent to the upper edges of the upper hood. sections, said clamping members extending across the said sectionsand engaging with the retaining means and being formed of-resilient material.

In testimony whereof, I have hereunto set my h nd and afiixed my seal.
